To all qvhom it may concern:

Be it known that'I, PAUL Wrens, a citizen of the United States, residingat Los Angeles, in'the county'of Los Angeles and State of California,have invented a new and useful Tractor, of which the following is aspecification. V

This invention relates to a tractor designed for operating plows orother implements or drawing vehicles, and one object of the invention isto provide a threewheeled structure by locating the two front wheels soclose together, and rigidly con- .nected' with veachg'other, that theyform a single wheel, capable of being readily swiveled in eitherdirectionto steer the tractor, andto'drive the said front'wheel at apoint between the two members thereof.

A further object is to provide for turning the said'fron't' wheelmembers as a unit transdownwardly directed rear members 2, sup

ported by a 'pair of rear wheels 3.

4 isa cross bar with an angular center portion 5 to which are attachedplows 6. The

cross bar 4 has forwardly extending arms 7 pivoted to trunnions 8 whichproject from br'ackets9 on a cross bar 10 and braced by struts 11. Anyother implement or device to be drawn may be secured to the cross bar 4in lieu of the plows .6.

' Under the front end of the frame 1 are i two wheel members 12 and 13and each wheel member consists of a hollow sleeve hub 14 having an innerflange l5 and an outer flange 16. Bolted to the outer flange 16 are bentspokes 17, the outer FEIWlSFX? which are boltcdbetween a centralci'rcuiar channel ring 18 and an outer circular angle ring 19, whilestraight spokes 20 are bolted to the rim for increasing the traction,as,

The sleeve hubs 14 are mounted to rotate on a stationary inner sleevebearing which has a central flange .26 bolted to a web 27 which extendsaround the sleeve bearing between the wheel members 12 and 13, and hastwo upwardly diverging-webbed arms 28 which are secured to a fifth wheel29 mounted to rotate underneath a stationary flanged ring 30, thefifthwheel 29 having a flanged ring 31'secured to its .upper side whichengages the flanged ring 30, securely locking the fifth wheel 29 theretoand permitting revolution thereon. The stationary ring 30 is secured tothe side frame members 1, as clearly shown in Fig. 3, and

' also to the cross bar 10 and to a cross bar The ring 31 is formed withan internal gear and meshing therewith is a pinion 34 mounted on a shaft35 journaled in a. bearing 36 which is formed on a cross ba 37. On theupper end of the shaft 35 is a worm gear 38 which meshes with a worm 39on a shaft 40, the shaft 40 being mounted in bearings 41 and extendingrearwardly to a bearing 42 and being operated by a hand wheel 43 whichis connected with shaft 40 by suitable gearing 44, so that by turninghand wheel 43, shaft 40 will operate the Worm gearing to revolveinternal gear 33 and front wheel members attached thereto.

Secured to the spokes 20 of the wheel member 12 is abeveled gear 45which meshes with a beveled pinion 46 secured to a vertical shaft 47,the lower end of shaft 47 being journale'din a bearing 48 on the webbedsupport 27, and the upper end at shaft 4'? extends loosely through the5th v i and carries a beveled'gear 49. The be ied gear 49 is adapted tomesh with a beveled gear 50 or 51 which are rigidly mounted on a sleeve52 which is splined on a shaft 53 which is driven from an engine 54through the medium of a clutch 55, the rear end of the shaft 53 beingjournaled in bearing 56, while itsforward portion is supported in thesleeve 52, the sleeve 52 being journaled in bearings 57011- the crossbar 3?. The sleeve 52 is slid in either direction by means of a forkedbracket 58' on the end of a link 59 operated by a lever 60 through themedium of pinion 50 or 51,,

drives gear 49 and shaft 47, thus rotating pinion 46 which drives bevelgear 45 and.

rotates the two wheel members 12 and 13, the two wheel members beingrigidly secured together by a bolt 62, the latter having shoulders 63which form abutments against which the sleeve hubs 14 of the Wheelmembers are secured by the nuts 63 on the bolt. The shoulders 63 spacethe sleeve hubs the proper distance apart to prevent undue friction onthe flange 26 of stationary sleeve and prevent lateral motion of thewheel members so that both wheel members turn as a single unit. Thefront wheel members 152- and 13 are driven in one direction by engagingpinion 50 with gear 49, while the reverse direction of drive is securedby sliding pinion 51 into engagement with gear 49 instead of pinion 50.

What I claim is 1. In a tractor, a frame, two wheel members, a framesupporting means supporting said frame and being revoluble thereon andextending between said wheel members, said wheel: members beingrevolubly connected thereto, means rigidly securing said whee]: membersto each other, and driving means extending between said wheel members toa point between a wheel and the frame portion which is between thewheels for rotating the same on said frame supporting means, saiddriving means extending to the frame from a point above the wheels andbeing concentric with the axis of revolution of said frame supportingmeans with respect to the frame.

2. A stationary frame, a steering frame pivoted on the stationary frame,a pair of wheel members close together mounted on the pivoted frame, andgearing extending from the stationary frame at a point above the wheelmembers to between the wheels on the pivoted frame for driving the same.

In testimony whereof I have hereunto set my hand at Los Angeles,California, this 31st day of December, 1912.
